Air Plan Disapproval; Missouri; Interstate Transport of Air Pollution for the 2015 8-Hour Ozone National Ambient Air Quality Standards

ENVIRONMENTAL PROTECTION AGENCY <CFR>40 CFR Part 52</CFR> <DEPDOC>[EPA-HQ-OAR-2021-0663; EPA-R07-OAR-2021-0851; FRL-11688-01-R7]</DEPDOC> <SUBJECT>Air Plan Disapproval; Missouri; Interstate Transport of Air Pollution for the 2015 8-Hour Ozone National Ambient Air Quality Standards</SUBJECT> <HD SOURCE="HED">AGENCY:</HD> Environmental Protection Agency (EPA). <HD SOURCE="HED">ACTION:</HD> Proposed rule. <SUM> <HD SOURCE="HED">SUMMARY:</HD> Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA or the Agency) is proposing to disapprove a State Implementation Plan (SIP) revision submitted by Missouri (the State) on November 1, 2022 regarding interstate transport for the 2015 8-hour ozone national ambient air quality standards (NAAQS). The “good neighbor” or “interstate transport” provision requires that each State's SIP contain adequate provisions to prohibit emissions from within the State from significantly contributing to nonattainment or interfering with maintenance of the NAAQS in other States. This requirement is part of the broader set of “infrastructure” requirements designed to ensure that the structural components of each State's air quality management program are adequate to meet the State's responsibilities under the CAA. Missouri previously submitted a SIP revision regarding ozone transport for the 2015 8-hour ozone NAAQS (2015 ozone NAAQS) on June 10, 2019, which the EPA previously disapproved. Missouri submitted a second SIP submission, reanalyzing its good neighbor obligations and making revisions to its SIP, on November 1, 2022. In this document, the EPA proposes to disapprove the November 1, 2022, submission as inadequate to address Missouri's obligations. This disapproval, if finalized, will establish a 2-year deadline for the EPA to promulgate a Federal Implementation Plan (FIP) to address the relevant interstate transport requirements, unless the EPA approves a subsequent SIP submission that meets these requirements. Disapproval does not start a mandatory sanctions clock. </SUM> <EFFDATE> <HD SOURCE="HED">DATES:</HD> Written comments must be received on or before September 20, 2024. <E T="03">Virtual public hearing:</E> The EPA will hold a virtual public hearing on August 21, 2024.
